Modification method of ceramic powder, microwave dielectric ceramic slurry as well as preparation method and application of microwave dielectric ceramic slurry
The invention belongs to the technical field of photocuring printing, and particularly relates to a modification method of ceramic powder, microwave dielectric ceramic slurry and a preparation method and application of the microwave dielectric ceramic slurry. The ceramic powder is subjected to surface functional modification, a siloxane group can be grafted on the surface of the ceramic powder, and an acrylate group is exposed on the surface of the ceramic powder, so that the ceramic powder has a photosensitive characteristic; the photosensitive group can be subjected to a polymerization reaction with an acrylate group in photosensitive resin used in the ceramic slurry so as to improve the curing performance of the ceramic slurry, the refractive index of ceramic powder can be greatly reduced, the widened curing depth Db of the slurry is improved under the condition of zero false curing width, meanwhile, the thickness of a curing layer during photocuring printing is increased, and the curing performance of the ceramic slurry is improved. The number of interlayer interfaces is reduced, the number of pore defects on the interlayer interfaces is reduced, and the density and the quality factor are improved. And the relatively high curing depth of the slurry is also beneficial to improving the printing efficiency, and the industrial production of the photocuring 3D printing radio frequency device is promoted.
本发明属于光固化打印技术领域，具体涉及一种陶瓷粉体的改性方法、微波介质陶瓷浆料及其制备方法和应用。本发明通过对陶瓷粉体进行表面功能化修饰，硅氧烷基团可以接枝在陶瓷粉体表面，接枝在陶瓷粉体表面裸露出丙烯酸酯基团，使得陶瓷粉体具有光敏特性，该光敏基团可以与陶瓷浆料中使用的光敏树脂中的丙烯酸酯基团进行聚合反应以进而提高陶瓷浆料的固化性能，可以大大降低陶瓷粉体折射率，在零误固化宽度下，提高浆料的增宽固化深度Db，同时，提高光固化打印时的固化层厚，使得层间界面的数量减少，层间界面上的孔隙缺陷数量减少，致密度和品质因数得以提高。浆料较高固化深度还有助于提高打印效率，促进光固化3D打印射频器件的工业化生产。
